Metallics JSTSP17SS316 – Frequently Asked Questions
1) Is the JSTSP17SS316 screw suitable for coastal or wet outdoor use?
Yes. These screws are 316 stainless, the marine grade with added molybdenum, so they hold up in salt spray, poolside, and wash-down environments far better than 304 stainless or plated carbon steel. That's the reason to pick this one over a cheaper zinc screw on exterior electrical work.
2) How many screws come in a jar of Metallics JSTSP17SS316?
100 screws per jar. The jar pack is the standard shop or van quantity for this fastener, so one order covers a run of box mounting or strap work without breaking into bulk boxes.
3) Will a pan head Phillips screw sit flush on an electrical box or strap?
No, a pan head sits proud of the surface by design. The JSTSP17SS316 has a broad, slightly domed pan head that bears on top of the material, which is what you want for clamping straps, boxes, and brackets. If you need the head buried flush in the surface, you need a flat head countersunk screw instead.
4) Do I need to pre-drill for the Metallics JSTSP17SS316?
Not in wood or thin sheet. The type 17 point on this 1-1/2 inch #8 screw cuts a relief as it drives, so it starts without a pilot and reduces splitting near board edges. In heavier steel it is not a substitute for a drill point screw.
5) What is the exact part number to order these 316 stainless screws?
Metallics part number JSTSP17SS316. That one number covers the #8-15 x 1-1/2 inch pan head Phillips type 17 screw in 316 stainless, packed 100 to a jar.
6) Can I mix these stainless screws with aluminum or galvanized hardware outdoors?
Be careful. 316 stainless in wet contact with aluminum or galvanized steel sets up galvanic corrosion, and the lighter metal corrodes first. For exterior work, pair this screw with stainless or isolate the joint. On wood framing and plastic boxes it is a non-issue.
